Lanza was found dead next to three guns, a semi-automatic .223-caliber Bushmaster rifle and two pistols made by Glock and Sig Sauer, a law enforcement source told CNN. All belonged to his mother.

Carver, who performed autopsies on seven of the victims, said the wounds he knew about were caused by a "long weapon." Asked by a reporter whether the rifle was the primary weapon, he responded, "Yes."

He spoke as police released a list of the names of ages of the victims. Twelve girls and eight boys were killed, all either 6 or 7 years old. The adults ranged in ages from 27 to 56, and included the school's principal, psychologist and at least two teachers.

Among those killed was Emilie Parker, 6.

"As the deep pain begins to settle into our hearts, we find comfort reflecting on the incredible person that Emilie was and how many lives that she was able to touch in her short time here on Earth," her father, Robbie Parker, told reporters, struggling to speak through tears.

He described his daughter as bright, creative and loving. She loved to draw pictures and try new things.

"Emilie's laughter was infectious and all those who had the pleasure to meet her would agree that this world is a better place because she has been in it," her father said.

Searching for answers in their deaths, major crime investigators police were combing "every crack and crevice" of the school.

They said they're finding some "very good evidence" there, and at the home of the shooter. Lanza's mother, Nancy, was killed at that house, authorities said.

"The detectives will certainly analyze everything and put a complete picture together of the evidence that they did obtain, and we're hopeful -- we're hopeful -- that it will paint a complete picture as to how and why this entire unfortunate incidence occurred," said Lt. J. Paul Vance, a spokesman for the Connecticut State Police.

Authorities, meanwhile, in Hoboken, New Jersey, were questioning Ryan Lanza, the suspected gunman's older brother, law enforcement sources said, though they did not label him a suspect. Lanza's father, Peter, who lives in Connecticut, was similarly questioned, one of the law enforcement officials said.

Peter Lanza released a statement Saturday expressing condolences to the families of victims.

"Our family is grieving along with all those who have been affected by this enormous tragedy. No words can truly express how heartbroken we are. We are in a state of disbelief and trying to find whatever answers we can," said the statement.

Two law enforcement sources said Adam Lanza lived with his mother. Contrary to early reports, they said, Nancy Lanza was not a teacher at Sandy Hook Elementary.

Nancy Lanza was a gun collector and recently showed off a newly bought rifle to fellow Newtown resident Dan Holmes, who owns a landscaping business in the town.

Besides the three weapons found at the school, Adam Lanza also had access to at least three more guns, a law enforcement source said. Investigators recovered a .45-caliber Henry Repeating Rifle, a .22-caliber Marlin Rifle and a .30-caliber Enfield Rifle, though it's unclear where they were found, the source said.

Investigators believe Lanza killed his mother and then took her guns and made his way to the elementary school wearing black fatigues and a military vest, according to a law enforcement official. Photos: Connecticut school shooting

Tragedy strikes at elementary school

Student: I saw bullets going past According to Vance, Lanza forced his way into the school though he wouldn't say how or whether Lanza used weapons to do it.

Authorities said it's also not clear whether Lanza entered before or after 9:30 a.m., the time each day when the school would lock its doors as part of a security system introduced this year. Authorities say the first emergency call about the shooting came in at "approximately" 9:30 a.m. Friday.

Within minutes, 26 people had been killed with chilling efficiency, leaving only the one wounded survivor. The survivor, an adult, has not been named.

"She has been treated and she'll be instrumental in this investigation, as I'm sure you can understand," Vance said.

The massacre in Newtown is the second-deadliest school shooting in U.S. history, behind the 2007 Virginia Tech mass shooting that left 32 dead.

"Stuff like this does not happen in Newtown," said Renee Burn, a teacher at another school in the town, which is roughly 75 miles northeast of New York City.

Until Friday, only one homicide in the past 10 years had been reported in the upscale community of expansive homes surrounded by woods, where many residents commute to jobs in Manhattan and the nearby Connecticut cities of Stamford and Hartford.

Flags were lowered to half-staff in a number of states, and vigils were held at houses of worship and at schools amid a national outpouring of grief.

i think the coroner can tell a shotgun wound from a rifle wound,maybe it never happened that was on the internet toooo

cut the fucking sarcasm asshole. This shit floating on the internet now is due to the media reporting on it. I saw this video that clearly had media reporting on it and figured it was true. especially when they said the report was from "state and federal officals" So don't get all, "the internet" when "state and federal officals" were the ones giving bogus info Unless Pete Williams was lying.

ok, I stand corrected then. I just saw that video with Williams sourcing "state and federal officials" on it and figured it was good to comment on. my bust. Thanks for having more tact in explaining than Blacken.

It's ok brah, I was doing the same thing, wondering why it was accepted as fact that they found and AR in the trunk and then suddenly it switched, couldn't figure out if it was the idiot media or someone attempting to use the situation to push an agenda.

Im still unsure. Although it does look like a Saiga being pulled from the trunk in the vid.

Looking at the video closer it does look more like a shotgun they're pulling out of the trunk but it's pretty blury. Still odd as hell how much this story was misreported or changed.

So it was an ar-15 used then?

During events like this eye witness accounts and even accounts going around the scene are almost always changed or misreported to some extent, so much information, much of which is speculation and unreliable eye witness accounts, is flying around a lot of stuff comes out that is just flat out wrong. A normal person put into a combat situation where bullets are flying by and little children are dying isn't in the right frame of mind to be giving accurate accounts of the events that took place, most people are freaking out beyond words and can barely function.
